[sv-bc] Re: [sv-ec] Confusion in casting expression

Hi Shalom,
Then the e.g. below:

module top;
    parameter p = 1;
    wire x = p'(1);
endmodule

Is wrong? But constant_primary can contain a simple parameter identifier 
too. So where it is defined in LRM what are the items inside 
constant_primary valid to be used as casting type?

Regards
Surya
